Solution

The correct option is B $N a < F e < C l < F < N e$
Solution:- (A) $N a < F e < C l < F < N e$
As we know that the ionization energy increases across a period but decreases down a group.
Hence the correct increasing order of ionization energy among the given elements is-
$N a < F e < C l < F < N e$
